27 | .SH NAME | |
28 | TIFFSetDirectory, TIFFSetSubDirectory \- set the current directory for an open | |
29 | .SM TIFF | |
30 | file | |
31 | .SH SYNOPSIS | |
32 | .B "#include <tiffio.h>" | |
33 | .sp | |
34 | .BI "int TIFFSetDirectory(TIFF *" tif ", tdir_t " dirnum ")" | |
35 | .br | |

37 | .SH DESCRIPTION | |
38 | .I TIFFSetDirectory | |
39 | changes the current directory and reads its contents with | |
40 | .IR TIFFReadDirectory . | |
41 | The parameter | |
42 | .I dirnum | |
43 | specifies the subfile/directory as an integer number, with the first directory | |
44 | numbered zero. | |
45 | .PP | |
46 | .I TIFFSetSubDirectory | |
47 | acts like | |
48 | .IR TIFFSetDirectory , | |
49 | except the directory is specified as a file offset instead of an index; this | |
50 | is required for accessing subdirectories linked through a | |
51 | .I SubIFD | |
52 | tag. | |
53 | .SH "RETURN VALUES" | |
54 | On successful return 1 is returned. Otherwise, 0 is returned if | |
55 | .I dirnum | |
56 | or | |
57 | .I diroff | |
58 | specifies a non-existent directory, or if an error was encountered while | |
59 | reading the directory's contents. | |
60 | .SH DIAGNOSTICS | |
61 | All error messages are directed to the | |
62 | .IR TIFFError (3TIFF) | |
63 | routine. | |
64 | .PP | |
65 | .BR "%s: Error fetching directory count" . | |
66 | An error was encountered while reading the ``directory count'' field. | |
67 | .PP | |
68 | .BR "%s: Error fetching directory link" . | |

70 | next directory in a file. | |
